A sterile rod made of metal or other material (e.g., carbon fibre) designed to be inserted into the intramedullary canal of any long bone [e.g., femur, tibia, humerus (including fixation of the glenoid), talus, fibula, radius, ulna] to immobilize by holding the ends of a fractured or diseased bone together (i.e., in position) for the purpose of joint fusion or arthrodesis (an operation to permanently fix a joint in position). The device is used for traumatic repair or reconstructive procedures; it may include screws if locked into place. This is a single-use device.
